FIG 9.

Effect of cardiolipin on a ΔtonB mutant growth. Bacterial growth on LBA (A) or LBA supplemented with 40 μM FeCl₃ (B) was recorded after incubation of petri plates at 37°C for 36 h. The bacterial strains used are as follows: 1, RAM3148 (wild type, ΔnapA::Km^r); 2, RAM3150 (ΔnapA::Km^r ΔtonB::scar); 3, RAM3151 (ΔnapA::Km^r ΔtonB::scar yejM1163); 4, RAM3153 (ΔtonB::scar ΔclsAB); 5, RAM3154 (ΔtonB::scar ΔclsAC); 6, RAM3155 (ΔtonB::scar ΔclsBC); 7, RAM3156 (ΔtonB::scar ΔclsABC); and 8, RAM3157 (ΔtonB::scar ΔclsABC napA::Km^r yejM1163).
